To allwlwm t mag/concern: Be it known that I, JOSEPH Poonrnnr, a subjectofthe Emperor of Austria, resident of Detroit, county lofVVaynaand Stateof Michigan, `have invented certain `nevi7 `and useful Improvements inAutomobile-Locks, of Which the following is 1 ai specification.`

This invention relates to improvements inlocks and particularly totypes`adapted to be applied f to automobiles," the locks being' of apermutativecharacter.

The principal obfect ofthe `invention is to provide a lockdii'liculttooperate except to one familiar with "the combination. Afurther object is to provide means whereby the several combinations' maybe readily changed. y i

These andother like objectsareattained by the novel `constructionandcombinations of parts, hereinafter described and shown in theaccompanying drawngs,forn1ing ainaterial part ofy this speciicatiom andin which` Figurel is a front elevational view showing a lock made inaccordancelvviththe invention. i i i y Fig.` 2 is a verticallsectionalvievv `taken on line-22 of Fig. 1.

Fig. 3` isa vertical sectional vievv` taken on lineB-BofFigQ. i i

Fig. 4 is another similar sectional view taken online 4-4 olf Fig. 2,`,and

Fig.4 5 is a fragmental perspectivejview shovvinga detail used, in`construction.` i

Figf is a detail view of one Aofitlielugrs and its beveled surfaces.

The invention comprises fa substantially rectangular casing,hav1ngasolicl back 10, joined to the floor or bottoinplatell and to thecoveror top plate 12,and the rigid cndsfl'and 14. i V

The entire front ofs the casing is? normally covered by a plate 15,pivoted at its bottomiona yrod 1G, While at the top is mounted arelatively narrow casing 18, containingr` a circular opening normally"covered by transparent plates 19, through `which `a target 20 can beseen when in a raised posi-` tion, the` same being supported by a flatstem 21, pivoted upon the scretv 22,1vvitliin Y the main portion ofthecasing;

Anl an,fgularly` disposed, `llat 1 extension 23 of `the flat stein 21contains a longitudinal slot@ Q4,-enga.qi1ip; With iaupin 25,1igjidlyset in plate 28, slidable `lol`1`,rltiidinally vvithin thel casmginslottedguides 29 securedto-the top and `bottom of the basing, stops30,"and

311"beingfformedivvith the plate.`

In .Fig 3 `the target is shown in dotted linesi-n `its loweredpositions.

JMotion `is communicated to the plate by an extendinghandler 35,\bent ata `right angle andoperable Within aslot 36, formed inthe hinged plate15. This i plate 15 is operable byme'ans of a knob 40, attached to `the"inner end of `which is a bent `latch 41, `engageable in atransversegroove formed in the lower side of the handle 35, so as to lock the samesecured to the inner side of the plate 15;

These push buttons are arrang'ed `in`two rows and arespaced equallyapart as `will be best seen in Fig. 1. Contactable With push buttons arecylindrical plungers` 52, the samebeing` supported inra fixed verticalplate 54, secured by eet to thebottom and ltopfvvalls of the container,and through which is a slottedopening forthehandle 35 to operate. All ofthese severalplungers `52iarealso supported by anotherlplate 58,

spaced outwardly from the rear vvall 10"`by means of Washers or collars59, While theex` v tending ends of the plungers are' pressed normallyoutwardfby bent flat springsGO, as can bestwbe seen in Fig. 2.... 1 y

Secured to `the outer face of the plate 54 are a pairfof s parallelguides 63, the same having undercut portions which `receivecorresponding tenons formed with a` sliding barl` `65, drawn `normallyrearward against the stop `66, by means ofvtensionspringl'?,

the `bar `z having; a; longitudinal undercut` slot i 70, Suited to theheads 71, of bolts 72, provided with winged nuts 7 3, by means of whichtransverse blocks 7 5, may be rigidly clampedto the bar. These blocks75, are formed with extending ends 77 having angular upper surfaces andmay be secured in any adjustment along the b ar 65 in accordancey withindex numerals 79 on its surface. Three of the movable blocks are used,the arrangement being such that the extending beveled ends 77 are clearof the plungers 52, each of .which isprovided with projecting lugs 80having similarbut oppositely beveled surfaces.

Each ofthe plungers 52 are grooved upon their sides. in suchmanner as toform two iat spaces 82 and 83, the same being fitted to `slideinlongitudinal slots 85 formed in the plate 28 so as to permit the plateto slide without interference with the plungers when the latter arepositioned to allow such movement.

Cranks 86 arel formed with the plungers, the same being slotted andhaving engaged therein links 88, extending upward normally to a uniformheight and bent outwardly forming handles 90, extending through slots 92in the stationary plate 54, in such manner that when the handles 90 areraised or lowered, the plungers 52 are turned correspondingly.

A lever 94: is pivoted near one end of the case upon a pin 95 and isprovided with a hook or catch 96 engageable with the handle 35, by meansof the spring 98, one end of which is secured to plate 54, and the otherto the longer limb 99 of the lever, which also carries an extendin pin100 contactable with the front end o? the slide bar 65, so as the sameis advanced, the hook is caused to release the handle.

Movement is transmitted through the slide bar 65 to the hook in thefollowing manner: The drawings lshow two uniform rows of push buttons46, which engage operatively with the plungers 52, pressing the sameinward, causing the beveled faces of the lugs 80 to engage with thecorrespondingly beveled ends 77 of the transverse blocks 75, three ofwhich are used and which have been clamped with relation to the rindex 79'-in any desiredV relation.

Let it be assumed that, asshown, the first block to the left is adjacentto numerals 1 in the second index, the second block adj acent to thenumerals 2 in the third index', the fourth row left blank and the thirdblock arranged with relation to the numeral 3 in the last index, thehandle 90, corresponding to the push button B,is raised, the plunger isin kposition to permit plate 28to be slid, and the handles correspondingto thev characters H and J are raisedr and are so set as toadmit'thecorresponding buttons to be pressed in and cause the lugs 80 tomake contact with the bevel ends 77. The plungers, other than the activeones, will prevent plate 28, from sliding if either 011e of saidplungers is operated.

The buttons however must be pressed in proper sequence as for instancethe button B upon being depressed moves the alined plunger inward,forcing its lug against the block clamped on the bar 65 so as t0 cause atooth 105, formed on said bar to engage with the rst tooth in a ratchet106, formed upon an extended portion of a pawl 108, pivoted on the screw109, and held in an engaging position by the spring 110 and having astem 111, passing through a slot 112 as can be seen in Fig. 4.

Let it now be assumed that the handle cOiresponding with the push buttonI-I is in a raised position, whereupon its depression moves the alinedplunger inwardly and forces its lug against the 'block which will bringthe inclined surface of the last named block in register with the lugson the plunger corresponding to the push button J which upon being'pushed inward causes the slide bar 65 to move the lever 99 to such anextent as to release the catch 96 from the handle 35 thereby permittingit to be pushed to the right and the plate 15 opened, so that access maybe had to the interior of the casing.

From the foregoing it will be obvious that a wide range of combinationscan be made by merely moving the blocks to various positions along theslide bar 65, the number of combinations being increased by arrangementof the handles 90.

l-laving thus described my invention what I claim as new and desire tosecure by Letters Patent, is- 1. In a lock, the combination with acasing and a plate normally covering the front thereo of a rigidvertical plate secured centrally in said casing, a plate parallelthereto and movable longitudinally within said casing, a slide barmounted on said rigid plate to move longitudinally of said casing, meansfor normally maintaining said bar in one position, a tooth formed onsaid bar, a pawl pivoted in said casing, a plurality of teeth formed onsaid pawl engagino with said tooth, means for pressing sai teethnormally in engagement, a knob and a grooved handle carried by saidplate, a bent latch attached to the inner end of said knob engaging thegroove in said handle for holding s aid plate in a normally closedposition, for limiting the movement of said slidin plate, a leverengaged with and operable y said slide bar, and means for progressivelyactuating said slide from the exterior of said cover plate. i

2. In a lock, the combination with a casing, a hinged plate for saidcasing, a plurality of push buttons extending therethrough, plungersengagcable with said push sition,`a slide har 'moyahle in said casing,and flat portions on sa1d plungers'for operating said sllde bar 1n apredetermined manner Jfor releasing said plate.

In testimony whereof I have affixed my signature.
